How to Accept Credit Card Payments on Your Website
A step-by-step guide for small businesses: payment links, hosted checkout, embedded forms, fees, PCI compliance and Wisconsin sales tax.
Short answer: the simplest way to accept credit cards on a small business website is a payment processor like Stripe or Square with a hosted checkout or payment link, so card numbers never touch your server. Expect processing fees of roughly 3% per online card transaction, and much less for ACH bank payments. A payment link takes minutes; a fully integrated checkout takes one to four days.
Four ways to take payments online
| Option | Best for | Effort |
|---|---|---|
| Payment links | Invoices, deposits, one-off sales | Minutes |
| Hosted checkout page | Small stores, bookings, donations | Days |
| Embedded payment form | Custom websites and apps | 1–3 weeks |
| Full ecommerce platform | Stores with many products | 2–8 weeks |
Step by step
- Choose a processor. Stripe, Square and PayPal are the usual choices for small businesses. Compare fees for your typical ticket size, plus ACH and in-person needs.
- Verify your business. You will provide your EIN or SSN, bank account and business details. Approval is usually quick.
- Pick the checkout style. Payment links and hosted checkout are the fastest and safest; embedded forms look more seamless.
- Turn on wallets. Apple Pay and Google Pay make mobile checkout one tap.
- Set up receipts and notifications. Customers get receipts automatically; you get an alert for each payment.
- Configure sales tax. Wisconsin's 5% state sales tax plus county taxes apply to many products and some services. Tools like Stripe Tax calculate it automatically; your accountant confirms what is taxable.
- Test, then go live. Run test payments, refunds and declined cards before switching to live mode.
Keeping it secure (PCI compliance)
Every business that accepts cards must follow the PCI DSS rules. When you use hosted checkout or processor-hosted card fields, card data never touches your systems, and most small merchants qualify for the shortest self-assessment questionnaire.
Lowering your fees
- Offer ACH bank payments for large invoices.
- Reduce failed payments with automatic retries and card updates.
- Avoid stacking several payment tools that each charge monthly fees.
